Abstract: The invention relates to a pneumatic cushion (1) having a base sheet (2) from which there project a plurality of adjacent inflatable cells (3) that are individually deformable in height. At least some of the cells (3) are internally fitted with respective individual sensors of cell deformation that deliver electrical signals indicating that a determined threshold of deformation of a cell (3) has been crossed.

Abstract: A nebulizer includes an arrangement for forming a mist from a liquid and an arrangement for delivering the mist to a patient. The delivery arrangement includes an air circulation passage having an air inlet and an outlet to the patient, between which the mist that is formed is taken up by a current of air, together with an outlet to the open air. The nebulizer also has an inlet check valve in the air inlet, an outlet check valve in the outlet to the open air and an arrangement for sensing the pressure in the conveyor means, together with an arrangement for delivering an indication or warning signal depending on the value of the signal supplied by the pressure sensing arrangement and for determining at least one indication or warning signal level threshold.

Abstract: A device for generating a mist from a liquid by a vibrating device. The device comprises a chamber which has a bottom wall on which the liquid rests, a side wall and a top wall. The chamber has at least one mist outlet orifice. The device includes a deflector which has a preferably concave or inclined underside at a distance above the bottom of the chamber and at a level lower than that of the top wall of the chamber.
